things to know about vaerlan sunmourne that are important. and yes, this includes his lore before my carrd gets made.
Vaerlan is quite literally the nicest man you'll ever meet despite what his face may say otherwise; it's clear that he has a strong sense of protection when it comes to his own people and the rest are often ignored. He has good reason as to why he's like this and even having this ideology would oft upset his wife, Belle'nor. It's not that Vaerlan didn't care for others outside the city and that of Quel'thalas, in fact, he cares far too much but there's a line that could never be crossed; his people mattered more since the scourge were beginning to be a threat. His people mattered more when Kael'thas falls into corruption and damning his people more. His people mattered more even after his wife and his little girl gets slaughtered by the attacks. His people mattered to him even if Lady Liadrin had forced his attention elsewhere with fear in her eyes. Fear of a man snapping and losing that divine faith of his. A man whose sword that'll be taken away while he's at the Sunwell keeping guard until he's assigned to assist a mage.
It's fresh air and an apology written by the one who he had fought beside for years.
Yet, it's a written death sentence on his own emotion regarding how he'll view his trust with the mage and this bond that'll be treated more a parental figure then just someone who protects. Even after the betrayal of the mage, it's a written death sentence when he returns home.
